HYDROCAEBQN MOTGR.

Application filed December 17, 1919.

T 0 all whom it may concern.

Be it known that I, LIONEL M. Voonson a citizen of the United States, and resident of Detroit, Wayne County, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon Motors, of which the following is a specification.

This invention relates to hydrocarbon motors and more particularly to mechanism for distributing gaseous fuel to the cylinders of hydrocarbon motors.

In a hydrocarbon motor such as is employed on motor vehicles and comprising four or more cylinders, one of the diiiicult problems which confronts the designer is to secure a uniform distribution of fuel to all of the cylinders of the motor. Another problem is to break up the fuel in such a manner as to insure its ready and efficient ignition,

The invention has for its objects, there fore, to overcome the above noted difficulties and to secure a uniform distribution of fuel to all of the cylinders of a hydrocarbon motor and also to break up the fuel so as to insure its ready ignition.

The mechanism by means of which the above objects are carried out comprises briefly a member interposed between the intake manifold of'a motor and the cylinders of the motor, this member in the embodiment of the invention illustrated consisting of a screen by means of which the gaseous fuel is broken up and is uniformly distributed tothe conduits which conduct the fuel to the cylinders.

One embodiment of the invention has been illustrated in the accompanying drawings, in which:

Figure 1 is a cross sectional view through the motor and intake manifold illustrating the screen in position between the manifold and the motor casing;

Figure 2 is an elevational view, partly broken away, at right angles to Figure 1;

Figure 3 is a transverse section of the construction shown in Figures 1 and 2 taken substantially at the longitudinal center thereof;

Figure I} is a section of the construction shown in Figure 2 taken substantially on the line 44 of Figure 2; and

Figure 5 is a sectional detail view illustrating, on an enlarged scale the screen construction.

Serial No. 345,587.

The motor in connection with which my improved fuel distributing means is illustrated has four cylinders, these cylinders being arranged in pairs.

As illustrated in Figure 1, the cylinder block of the motor is provided with an elon gated passage or chamber 10 into which the gaseous fuel passes from the intake manifold and from which the fuel is conducted through conduits l]. to the two pairs of cylinders. The elongated passage 10 in the cylinder block is open on one side and the intake manifold 12 is securely bolted to the block over the passage 10 and my improved distributing device is bolted between the manifold and. the motor casing.

In the present invention tl device has been combined with the gasket 13. the gasket comprising a pair of substantially parallel flat plates 14, these plates being connected together in any suitable manner, or, if desired. being formed integral with each other. Suitable packing material 15, preferably formed of asbestos. is interposed between the two plates 14-. two layers of this material being illustrated. in Figures 4; and 5. A screen 16 is positioned between the two lay ers of packing and extends throughout the entire space between the members 14. As illustrated particularly in Figure 5, one of the plates overlaps the other and is crimped or clamped on to this member, thereby retaining the plates 14 together and also clamping the screen between these me1n bers.

The gasket 13 is iirovided with a plurality of apertures adjacent its outer edge portion for the passage of bolts 17 for retaining the gasket and the manifold in position on the casing of the motor. In addition to this se curing means for the screen and for the members 14 above described, several rirets 18 are provided adjacent the ends of the gasket. these rivets being headed over and providing for the passage of water conduits to the water jacket 19 which surrounds the intake manifold.

My improved fuel distributing means operates as follows:

Then the fuel enters the intake manifold from the carburetor, the screen although not retarding the passage of the fuel to a suliicient extent to interfere with the operation of the motor does sli htly retard the fuel passage to an extent sufiicient to insure the uni form distribution of the fuel over the entire surface of the screen and, therefore, a uniform distribution to the conduits 11, which conduct the fuel to the motor cylinders. It will be obvious that this result could not be obta'ned by interposing the screens in the conduits which conduct the fuel to the intake manifold since screens disposed in such a position would delay the passage of the fuel to such an extent as to interfere with the eflicient operation of the motor.

In addition to securing the uniform dis tribution of the fuel to the cylinders of the motor, the screen also breaks up the fuel passing from the manifold to the motor in such a manner as to insure its ready ignition in the cylinders.

t should also be noted that my improved device utilizes the gasket as a retaining means and in this manner avoids the use of additional parts and also securely retains the screen in position.

IVhile I have in the above specification described one specific embodiment of my invention, it should be understood that changes may be made without departing from the spirit or scope of the invention as expressed by the following claims.

hat I claim and desire to secure by Letters Patent is:

1. In combination, a hydrocarbon motor comprising a plurality of cylinders, an elongated intake manifold secured to said motor and adapted to conduct the mixture to said cylinders, and means extending throughout the length of said manifold and interposed between said intake manifold and the cylinders of said motor for securing a uniform distribution of fuel to said cylinders.

2. In combination, a hydrocarbon motor comprising a plurality of cylinders, an elongated intake manifold secured to said motor, and means extending throughout the length of the manifold and interposed be-, tween said intake manifold and the cylinders of said motor for breaking up the fuel entering said cylinders from the manifold.

3. In combination, a hydrocarbon motor comprising a plurality of cylinders, an intake manifold secured to said motor, and single means interposed between said intake manifold and the cylinders of said motor and extending throughout the length of the manifold for breaking up the fuel entering said cylinders from the manifold and for securing a uniform distribution of the fuel to said cylinders.

4'. In combination, a hydrocarbon motor comprising a plurality of cylinders, an intake manifold, a gasket between said intake manifold and the casing of said motor, and means carried by said gasket for securing a uniform distribution of fuel to said cylinders.

5. In combination, a hydrocarbon motor comprising a cylinder block having a plurality of cylinders, an intake manifold, a gasket between said manifold and the cylinder block of said motor, and a screen carried by said gasket for securing a uniform distribution of fuel to said cylinders and for breaking up the fuel entering said cylinders from said manifold.

6. In a hydrocarbon motor, the combination with a cylinder block having an elongated passage for the inlet gases, said passage being open along one side thereof, of an elongated intake manifold adapted to be secured to the cylinder block over the open part of said passage, and means interposed between said manifold and the cylinder block for securing a uniform distribution of fuel to the cylinders.

7. In a hydrocarbon motor, the combination with a cylinder block having an elongated passage for the inlet gases, said passage being open along one side thereof, of an elongated intake manifold adapted to be secured to the cylinder block over the open part of said passage, and a screen inter.- posed between the manifold and cylinder block for the purpose set forth.

8. In a hydrocarbon motor, the combination with a cylinder block having an elongated passage for the inlet gases, said passage being open along one side thereof, of an elongated intake manifold adapted to be secured to the cylinder block over the open part of said passage, and a gasket between the manifold and cylinder block and having an opening for the passage of the fuel, said gasket havig a screen secured thereto covering the opening therein.

In testimony whereof I affix my signature.
